Query reusable multiband HNR statistics

Extract mean and standard deviation from a reusable set of multiband `Harmonicity` objects built by [build_multiband_harmonicity()]. This is the cheap query step for repeated interval workflows.

Usage

multiband_hnr_stats(multiband, from_time = 0, to_time = 0)

Arguments

multiband

Named list of 5 `Harmonicity` objects (or Harmonicity external pointers), typically returned by [build_multiband_harmonicity()].

from_time

Start time for statistics extraction (default `0`)

to_time

End time for statistics extraction (default `0`)

Value

Named list with the same `*_mean` / `*_sd` fields as [calculate_multiband_hnr_ultra()].

Examples

sound <- Sound$create_tone(frequency = 150, duration = 1, sampling_rate =
 16000)

built <- build_multiband_harmonicity(sound)
hnr_interval1 <- multiband_hnr_stats(built, 0, 0.5)
hnr_interval2 <- multiband_hnr_stats(built, 0.5, 1.0)
